Do you sweat more if you drink more water?

If you’ve ever stopped to wonder about this process, you’re not alone. Many people find that they sweat a lot more when they’ve been drinking water, but you may not know whether or not this is normal. There are also other contributing factors that can lead to increased sweating aside from just drinking more water. So how can you tell if the two are related in your situation?

In this article, we’ll help you understand a little bit more about sweating and water intake. You’ll find out the ways they’re related and what may happen to your body—and your sweat—if you’re either getting too much water or not enough. You’ll even learn a little bit more about how sweat works overall.

But is there any reason why sweat might be related to your water intake? Does sweat help you release fluids from your body? It absolutely does, and we will expand more on this information below.

By the time you finish reading through this article, you should be well informed about the process of sweating and how the water you drink affects it. So let’s get started!

Sweat and Water

Some people just generally sweat a lot more, while others sweat more because of a health reason or genetic condition. In this section, we’ll break down the information you need to understand what may be causing your increased sweating situation. There’s a chance it’s related to the water you’re drinking, and below, we’ll give you plenty of information to help you figure out whether or not this may be going on with you. Sweat and water have a lot to do with each other, especially since sweat flushes excess fluid out of your body along with other substances. Here are a few facts about how sweat and water are related:

  • If you drink far too much water in a day, you may experience hyperhidrosis, which is dangerous. This condition is linked to a genetic predisposition and can potentially cause you to sweat out so much fluid and electrolytes that you stay in a state of dehydration. This can, over time, severely contribute to other potential health problems and concerns.
  • Hyperhidrosis is a condition that causes excessive, nearly constant sweating, especially on the hands and feet. It may cause sweating elsewhere on the body and can also lead to overall excessive sweating, but for the most part, it is limited to the hands and feet. If you have several family members who experience this already and you start to experience it as well, speak to your doctor. There are medications that can be used to treat this condition before it gets out of hand.

    People who work out frequently drink more water to have more fluid available for sweating. Therefore, if you’re the type of person who has long workouts on a regular basis, or if you go for long runs and you work up a significant sweat, you need to make sure you’re drinking enough water to compensate your body for this loss in fluids. Athletes may need to drink electrolyte water or sports drinks to keep up with everything the body loses when sweating, but most people should be fine simply drinking more water. The more water you have in your body, the more fluid your body has to sweat out. This is healthy and natural.

    Not drinking enough water before and during a workout means you get hotter faster, since you may not be sweating enough. Sweat naturally cools the body down, which is why our bodies start sweating as soon as they feel too warm. However, if you haven’t had enough to drink and you work out, even for a short amount of time, your body won’t have enough fluid available to produce sweat. Therefore, you’re going to feel hotter sooner, and you will not be able to keep up with the endurance you need to complete your workout. This is one of the many reasons why it’s crucial to drink plenty of water before, during, and after a workout, no matter how long or short it might be.

    Some people simply sweat more than others, regardless of how much water is consumed. You may not have a genetic condition or illness causing it, and you may drink the right volume of water every day for your body. Depending on your body and your own individual experience, it’s possible that you still might end up sweating more than you think you should. Some people are naturally sweaty, and this is not anything abnormal or anything you should be worried about. However, if you find that it’s bothering you and you want to seek a solution, be sure to talk to your doctor about it.


Did you learn something useful about your relationship between water and sweating? Keep in mind that the information listed above may not be true of everyone, and that each individual experience is different. If you find yourself dealing with an overabundance of sweat and you think it’s from drinking too much water, you’re not alone, but you may still want to speak to your doctor about this if it’s a new issue. As with any changes in your body, it’s a good idea to have this problem evaluated by a professional.

Keep in mind, too, that not everyone experiences hyperhidrosis. This is a largely genetic condition, so if you aren’t already predisposed to it, you may not experience it at all. This doesn’t mean you can’t, but it means you’re less likely to. Only your doctor will be able to tell you for sure if this is what you’re dealing with.

If you sweat more, should you drink more water? If you find yourself sweating from something you know is causing the sweat, like working out or working hard, you should definitely drink more water to replenish what you’re losing.  You should also make sure you’re drinking enough water and eating enough food to keep up your electrolyte intake.

However, if you’re sweating more than you usually do and you think it is from drinking too much water, make sure you cut back on your water intake for a couple of days to see if this makes a difference. If you find that your sweat diminishes from reducing your water intake, keep it up, as long as you’re getting enough in a day.

Always make sure you’re drinking enough water every day to keep your body from becoming dehydrated so that when you do sweat, there’s enough fluid in your system to cover it.
